nodejs过滤输入

Question

In PHP to filter inputs data I use functions htmlspecialchars and mysql_real_escape_string. Is there any functions like this in nodejs?

I need to check all inputs in my rounter functions to prevent hacker attacks like xss. Thanks!

Answer 1

node-validator is the perfect library for this, it has many functions for both validation and sanitation / filtering, for example:

entityDecode()                  //Decode HTML entities
entityEncode()
xss()                           //Remove common XSS attack vectors from text (default)
xss(true)                       //Remove common XSS attack vectors from images

or

contains(str)
notContains(str)
regex(pattern, modifiers)       //Usage: regex(/[a-z]/i) or regex('[a-z]','i')
notRegex(pattern, modifiers)
len(min, max)                   //max is optional
isUUID(version)                 //Version can be 3 or 4 or empty, see http://en.wikipedia.org/wiki/Universally_unique_identifier
isDate()                        //Uses Date.parse() - regex is probably a better choice
isAfter(date)                   //Argument is optional and defaults to today
isBefore(date)                  //Argument is optional and defaults to today
isIn(options)                   //Accepts an array or string
